A TELECOMMUNICATION SYSTEM

Abstract: In a telecommunication system (1) a central receiving unit (2) is coupled with several devices (4) via a transmission network (3), which devices (4) transmit data input with the aid of data input means (8) to the central receiving unit (2), usually within a short period of time. The data transmitted has at least partly been created on the basis of interactive communication with for example a television programme (6) being broadcast. The data to be transmitted is stored in a temporary memory (10) of the device (4), in groups accessible for being read jointly. The device (4) comprises a local processing unit (9) coupled with the temporary memory (10), by means of which said joint reading is started on command and the groups of input data are made ready for being transmitted contiguous thereto. Due to the resulting compact set-up of the data to be transmitted the transmission network (3) is occupied only briefly and congestion problems are reduced.

Description: A TELECOMMUNICATION SYSTEM The present invention relates to a telecommunication system, comprising a central receiving unit, a transmission network and at least one device, each being coupled with said transmission network and being provided with data input means, for transmitting data to the central receiving unit. Telecommunication systems which are arranged in the manner indicated above are known in the digital communication industry, and are especially used in for example computer or telemetry systems and/or in speech communication, which may or may not be mobile speech communication, irrespective of the fact whether said communication takes place over comparatively small distances or over larger distances, for example intercontinental, for example via satellites. In those cases where several transmitters or transceivers wish to communicate with a central receiving or transceiving unit via a transmission network or transmission channel in a certain manner, as may for example be the case in telephone systems, the transmission network is occupied in such manner as to make it impossible for other parties connected to the same network to use the same channel, which is often the only channel, in the transmission network at that point of time. In the present telephone systems it is necessary to redial the same number in case the party called or the receiver is engaged. In order to facilitate said dialling the current telephones, which transfer speech in two directions, have a permanent memory, in which a group of associated data is stored in each memory location with a view to said one group being read. Due to the current intensifying use of transmission networks blocking or congestion problems arise, therefore. As a result of the present intense occupation of the transmission network each form of communication via the transmission network has appeared to be impossible under certain circumstances. This is unacceptable, however, especially with certain forms of communication, since it is in the public interest that a number of instances, think for example of the police, the fire brigade, hospitals and the like, can be reached at all times. Still the perception seems to be growing that a further intensification of telecommunication, in particular via telephone or cable networks or via glass fibre networks provides possibilities for offering a multitude of further services in the broadest sense of the word, in particular with a view to an active participation or interactive communication of the general public. The known telecommunication systems, however, have appeared to be less well suited for enabling an active participation of for example a public of millions, let alone that this happens in a technical manner, whereby acceptance by the said public takes place smoothly. The object of the present, invention is to provide a telecommunication system which generally comprises a large number of devices, which can be operated in a simple manner which is readily acceptable for the general public, utilizing transmission networks which are already generally used, such as telephone networks, central antenna networks or other networks, in a manner which moreover allows active or interactive participation by the general public in a comfortable manner. In order to accomplish that objective the telecommunication system according to the invention is characterized in that said device comprises a temporary memory for the storage of groups of input data accessible for being read jointly, and that said device comprises a local processing unit coupled to said temporary memory for starting said joint reading at the command of the local processing unit and for making said groups of input data ready for transmission, whereby each device possesses a timer connected to said local processing unit, said timer having a period time which determines the time of transmission, which point of time is slightly different for each timer (statistically) . The advantage of the telecommunication system according to the invention is that the input, the storage and the eventual making ready for transmission of the data to be transmitted takes place prior to the actual transmission of said data, namely at a time when the transmission network is not occupied yet. The internal organisation of the compact structure of the said data preceding transmission moreover ensures a short duration of the transmission, with the result that the transmission network is occupied only briefly, as a result of which the risk of congestion problems is reduced. Advantageous is furthermore the fact that the memory may be a temporary memory, because the data may be erased from the memory after being transmitted, as a result of which the memory only requires a small amount of energy during a relatively short time for storing data. In its • simplest form the device only needs to be provided with means for transmitting the data and not necessarily with means for receiving any information to be transmitted to the devices by the central receiving unit via the transmission network. Generally this will allow a simpler design of the devices. A further advantage is that when a command to read the data and make them ready for transmission, and to actually transmit the data is given on the basis of the timer, this transmission will in principle also take place at random, seen from a statistical point of view, as a result of which the possibility of several devices within the telecommunication system wishing to transmit simultaneously or during overlapping periods of time, which may lead to congestion problems, has been reduced. But even if the period times of the timer in the various devices are deterministic, and it is therefore accurately known at what moments actual transfer of data takes place after the starting command has been given, the risk of congestion will be reduced, partly due to the fact that no synchronisation takes place among the locals timer within the device, since the different period times in practice do not have to lead to transmission of data being started at the same time. It will be apparent that it is to be preferred to keep the transmission time itself as brief as possible, in order to further reduce the congestion problems. One embodiment of the telecommunication system according to the invention is characterized in that the device is provided with transmission means connected to the local processing unit, which are activated at the command of said local processing unit. If there is a possibility that the data to be transmitted has not been received after a first transmission to the central receiving unit, said transmission may be repeated by the transmission means until the transmission has been successful. In practice this actual transfer of data from all devices to the central receiving unit is not always necessary for that matter. Think for example of those cases where only one representative random check may be taken, for example within one hour, during a radio or television broadcast. Another embodiment of the telecommunication system according to the invention is characterized in that the transmission network is of the type which carries a signal when transmission of data to the central receiving unit is allowed. The advantage of this embodiment is that the transmission of data does not need to take place at random, but that the transmission of data will take place successfully directly after the signal present on the transmission network is detected by the device. Thus retransmission has become redundant. Another preferred embodiment of the telecommunication system according to the invention is characterized in that with a view to further reduce the congestion problems, the period times are interrelated in a manner which results in data transmission times which are connected in accordance with the magnitudes of the elements of an arithmetic progression. In this case simple implementation, using the digital means of the timer, is possible. A concrete embodiment is for example an embodiment wherein the transmission times are spaced apart, by a 5-second interval for example, a whole number of times in a deterministic manner. Yet another embodiment of the telecommunication system according to the invention is characterized in that additional data to be processed in the central receiving unit is combined with the groups of input data to form a compact package of data to be transmitted. The advantage of a compact package being transmitted is that actual transmission will only take little time in that case, as a result of which the transmission network is occupied only briefly. Said additional data usually comprises selection or call data, which may be utilized in the transmission network, if necessary, in order to be able to select the central receiving unit as the party being called, for example when being used in the public telephone network. Said further data inter alia comprises unique data, such as the subscriber number or for example the identity of the subscribers or of the person who has input the groups of data in the temporary memory with the help of the data input means. Another preferred embodiment of the telecommunication system according to the invention is characterized in that said device comprises a temporary memory for the storage of groups of input data accessible for being read jointly, and that said device comprises a local processing unit coupled with said temporary memory for starting the joint reading and making ready for transmission of the groups of input data at the command of the local processing unit, whereby said data input means comprise a keyboard, which is arranged for placing a template or mask thereon, which will cover those keys on the keyboard which are not programmed at that point of time. The advantage is that the template or mask offers possibilities for several devices and operators to participate interactively with several radio or television networks simultaneously, insofar as the same keys on the keyboard are not simultaneously programmed for different programmes, of course. Furthermore it is possible to participate in different programmes with one and the same device at different times, interactively if desired, by simply exchanging the template between programmes. If desired the templates may for example be provided with publicity or instructions for use, or contain data or illustrations of programmes to be broadcast or explanatory information. The templates may be purchased from a newsstand, for example, or be appended to a magazine or weekly or be sent to people's homes in case they wish to take part in an action on radio or television. In one possible embodiment of the telecommunication system according to the invention the template is provided with openings, through which access can be gained to the keys of the keyboard located under said openings. Another embodiment of the telecommunication system comprises a central transceiving unit, a transmission network and at least one device, each being coupled with said central transceiving unit and being provided with data input and output means, for communication with the central transceiving unit, whereby said data output means comprise a display unit, which embodiment is according to the invention characterized in that said device comprises a template memory for the storage of at least part (inclusively in the order of nil or the integer) of the data required for the eventual local set-up of a virtual template to be displayed on said display unit, whereby the complementary part (inclusively in the order of the integer or nil) of the data required for the local set-up may be made available (downloaded) by the central transceiving unit. The advantage of this is that it is no longer necessary to maintain an apparatus for manufacturing, distributing, offering for sale and obtaining payment for the templates. Instead of this the complementary part of the data required for locally preparing the template is not supplied to a user on demand until the sum of the virtual template has been paid. Alternatively, if all the information is already present locally, the key(s) required for setting up the template are not supplied until all sums have been paid, or all information required is downloaded from the central unit to the device once all money due has been paid. In that case there is no need to maintain the apparatus, which has thus become redundant. The present invention will be explained in more detail with reference to the accompanying drawing. The drawing comprises Figures, in which like parts are numbered alike, and in which: Figure 1 schematically shows a preferred embodiment of the telecommunication system and the device for use in said telecommunication system; Figure 2 shows the possible exterior of the device for use in the telecommunication system of Figure 1; Figure 4 shows a possible embodiment of the template for use on the device of Figure 2; and Figure 3 schematically shows an implementation of a system in which the telecommunication system, the device and the template according to the invention find application. Figure 1 shows a telecommunication system 1, comprising a central receiving unit 2, which is coupled, through a transmission network 3, to a device 4, whose exterior is shown in Figure 2. Several such devices 4 are connected to the transmission network 3. Only one of said devices 4 is shown in the Figure. Usually the transmission network 3 contains amplifiers, switching stations or processing units, which are not explained in more detail within the framework of the description of this Figure. The transmission network 3 may for example be a telephone network already present, or a central antenna cable network or an ISDN-like network, or be comprised of a glass fibre network. If the transmission network is for example a telephone network, the device 4 may be connected to the telephone network together with the telephone devices which are usually present. In case of a telephone network it will be easy for the administrator of the network to charge costs to the possessor of the device 4, that is the subscriber, usually in proportion to the duration of the communication over the transmission network 3. In its simplest form the transmission network 3 only needs to be suitable for transmitting data in the direction of the device 4 to the central receiving unit 2. If the device 4 is of a more advanced design the device, as well as the transmission network 4, will be suitable for exchanging information in two opposite directions. In that case it is a transceiver, therefore. The data transmitted to the central receiving unit 2 by the various devices 4 is processed in the receiving unit 2 and can be used directly there, for example in a studio 5, in which a programme 6 (schematically indicated) is recorded, which programme is available to viewers of a television 7 upon being broadcast, which viewers can participate interactively in the programme 6, dependent on the contents of the programme, by transmitting data to the central receiving unit 2 by means of the device 4. The device 4 is provided with data input means 8, usually in the shape of a keyboard, to be used for inputting data. The device 4 furthermore comprises a local processing unit 9 coupled to the keyboard 8 and the transmission network 3. In addition to the local memory, usually in the form of a ROM or a RAM, which is necessary for the operation of the local processing unit 9, also a temporary memory 10 is coupled with the processing unit 9. On the basis of questions asked in the programme 6 the respective replies are input in the device 4 by the operator of the device 4, by pushing the appropriate buttons (yet to be explained) on the keyboard 8. Each reply or series of replies constitutes a group and the groups are successively stored in the temporary memory 10, in a manner which makes it possible to read the temporary memory 10 in its entirety by means of the processing unit 9. Also in case only one reply is transmitted more than one group will usually be transmitted, because in addition to the group comprising the one reply also a group of data, which will for example comprise the identification of the receiving unit and/or the transmitting device, will be transmitted. The device 4 is provided with a command key 11, which makes it possible for the data in question to be transmitted to the central receiving unit 2 over the transmission network 3, by means of the local processing unit 9, usually by using suitable transmission means 12 and by following a prescribed protocol. The compactness of the data then transmitted determines the duration of the transmission of the data to the receiving unit 2 to a considerable degree. When the respective channel in the transmission network 3 to the receiving unit 2 allows so, the highest possible transmission speed is selected, in order that the transmission of information to the receiving unit 2 again lasts as briefly as possible and congestion problems can thus be avoided. Only after the data has been made ready for transmission by the local processing unit 9, at the command of the command key 11, the actual brief transmission of said data will take place. The device 4 is provided with a local clock or timer 13, which is usually necessary for the internal synchronisation of the local processing unit 9, which is provided with a microprocessor in most cases. When the local timers 13 of the various devices 4 provide the local synchronisation in a device 4 at mutually different rhythms, using different period times, which will result in information being transmitted to the receiving unit 2 at times which are mutually divergent, random or pseudo-random among the various devices 4, this will reduce the risk of congestion. This will be explained in more detail hereafter. It is also possible, however, that a central timer in the central receiving unit 2 prescribes which of the respective devices 4 and in which order said devices are allowed to transmit the information stored in their memories over the transmission network 3. The existing telephone transmission network does not provide for this, however. When the period times and in particular the starting times of the transmission of information to the receiving unit 2 derived therefrom are mutually divergent, which is for example the case when said starting times in the various devices 4 are interrelated in accordance with the magnitudes of the elements of an arithmetic progression, the possibility of congestion will be further reduced. The device 4 is provided with a read/write unit 14 to be used for a memory card, a magnetic card, a smart card or a chip card 15. The card 15 may or may not be provided with electric contacts, or be suitable for being read/and or written on magnetically as well as for containing electric, magnetic, mechanical and/or optical data, for example bar code data. In most cases certain parts of the card cannot be written on by the operator of the device 4 himself, although reading is usually possible in order to add the identity of the subscriber of the device 4 to the data being transmitted to the central receiving unit 2, if desired. Of course it will be possible to transmit programme codes along with the data, or other codes which make it possible for the central receiving unit 2 to select to what programme the data received relates or to what question the data in question relates. In some cases also data relating to the identity of the subscriber is transmitted along with the other data. When orders are placed by means of the device 4, the identity of the subscriber is indeed relevant, of course, but when polls or other anonymous activities are being conducted the opposite is the case. Protection of the device 4 may take place by indicated by: A, B, C, D, to show that the operator must select one of said four possibilities once or a number of times. Of course also the other keys on the keyboard 8 may be permanently accessible, to make it possible to perform certain fixed functions. Although the programming and allocating of functions to keys might in principle be done by the central receiving unit 2, if the device 4 were also suitable for receiving information from the transmission network 3, a directly practicable solution is a solution whereby the allocation of the functions in question to keys on the keyboard 8 takes place on the basis of information read from the card 15 by means of unit 14. The card 15 may contain information for allocating functions to a group of keys, but also to several groups of keys for different interactive programmes, if desired. A maximum flexibility with regard to the programming of keys is achieved. For example, during a first period a first group of keys may be allocated or hired out to a first programme, which is broadcast at a first transmitting frequency, whilst during a second period, which may very well overlap said first period, another second group of keys is allocated to another second programme, which may or may not be broadcast at the same time at a second transmitting frequency, etc. The device 4 is provided with means 20 for holding down the template 18 on the keyboard. The keyboard 8, the display unit 16 and/or the read/write unit 14 are preferably housed within one convenient housing. Figure 1 shows that the read/write unit 14 is provided with switch means 21, which are arranged in such a manner that the device 4 can be operated as soon and as long as the card 15 is inserted in the read/write 14. The device 4 is preferably provided with a power supply unit 22, in order to keep the amount of electric energy that is withdrawn from the telephone network for feeding as low as possible. The power supply unit 22 is connected to the switch means 21, so that the device 4 only operates or receives supply known at the receiving end, to be allocated to each device 4, which is encoded in a manner known at the receiving end. In this way a unique transmission time may be determined for each device, which is only known at the end of the central receiving unit. This renders the system fraud- proof. When congestion occurs with one or more other devices during a transmission attempt, a next transmission time known to the receiving unit may be determined, for example on the basis of a next number in a series of permutated numbers, of which the actual permutation is only known to the receiving unit. When only one group of data is transmitted to the receiving unit 2 by a device 4, this group will usually contain data that does not make it necessary or desirable for the receiving unit 2 to be able to identify the transmitting device 1. In that case the group does not contain any identification data, but for example opinion data or the like. When the user participates in a quiz, lottery or game, for example, or when orders are placed, the data containing the identity is sent along, however. In that case the data will also contain name/address/residence information and/or Giro and bank information and the like, so that when an order is placed for which a certain amount has to be paid, this amount can be debited from the bank or postal account. Possibly the device 4 will contain a second read/write unit 14' (not shown) , similar to the read/write unit 14, in which a second card 15' (not shown), similar to the card 15, may be inserted, which card contains information representing money or being equivalent thereto and which is debited by the unit 14' at the command of the receiving unit 2 upon acceptation/registration of the order. The identification data is read from the card 15, for example when the correct PIN code is input, whereby the card will then transmit the data, for example in encoded form. Alternatively the encoded PIN code or another unique code is for example transmitted on the card 15, so that the group of data to be transmitted remains small, whereby the central receiving unit 2 will search the identification data associated with the code received, thus making the identity of the party placing the order known by the central receiving unit. In another embodiment the device 4 comprises a (usually permanent) memory, hereinafter called the template memory. Said template memory may be detachable and for example contain a ROM, CD-ROM, CD-I, CD-RAM, CCD or the like. It may also be a chip card, memory card, smart card, magnetic card or similar card 15, 15', however, which may be inserted in the read/write unit 14, 14' . Although in principle the device 4 may contain all information required for locally setting up a virtual, that is an at least partially software-implemented template or mask, usually a complementary data part is required in addition to the data part stored in the template memory, in order to complete the template. Said complementary part, which for example contains a software-implemented key for accessing the information, whether or not in encoded form, which is stored in the template memory, is made available (downloaded) from the central unit 2 by the device 4 on request, in a manner yet to be explained. In spite of the fact that extensive information is available in the device 4 in that case, the transmission network is occupied very briefly and the transmission time is very short, at least if not all the information has to originate from the unit 2. The software-implemented template to be displayed on the display unit 16, which usually contains graphic and/or textual information, may be combined with the previously explained template 18, which only provides access to predetermined keys on the keyboard 8 being programmed at that point of time. The virtual template uses keys or blocks to be activated by hand or by means of tools, such as a reading pen, mouse or the like, whereby one or more additional templates are displayed on the display unit 16 as vo vo o. O not by means of the telecommunication system. The system 1 includes code selection means 60, which select the code of the required offerer 50, who is to perform the service requested, on the basis of the code data included in the data transmitted to the unit 2. The data transmitted furthermore contains transaction data, which records the contents of the transaction requested, which contents have been indicated before on a respective, real (material) or virtual template by the user 40. The code data has for example been input by the user himself, been read from a card or from the template memory or originate from the template, which contains this data in an electrical, magnetic, mechanical and/or optical manner. Of course it depends on the kind of transaction whether the data transmitted does or does not contain identification data. In case for example two devices 4 wish to transfer fax messages to each other, at least one of said devices will be provided with video or scanning means, and a transmitting user 40 will be able to transmit a fax message, which will usually contain textual, photographic or graphic information, to a mailbox memory in for example the receiving device 40 by inputting an appropriate code. If the receiving unit 2 is active, also direct communication may take place without the intermediary of the mailbox memory, if desired. Usually the device 4 will be provided with a printing device (printer) , which may or may not be an external printing device.
